Ingredients Quantity

This recipe balances bold flavors and creamy textures with a carefully curated list of ingredients. Here’s what you’ll need:

  • 6 tbsp salted butter
  • 4 medium yellow onions, thinly sliced
  • 1 1/4 cups dry white wine (e.g., Pinot Grigio or Sauvignon Blanc)
  • 3 garlic cloves, minced
  • 2 cups cremini or wild mushrooms, sliced
  • 2 tbsp fresh thyme leaves
  • 2 tbsp chopped fresh sage
  • 1 tsp honey
  • 6-8 cups low-sodium chicken or vegetable broth
  • 2 tsp Worcestershire sauce (or soy sauce)
  • 2 bay leaves
  • 1/2 cup heavy cream
  • 6 slices French bread
  • 2 cups shredded Gruyère cheese
  • Kosher salt and freshly ground black pepper to taste

Optional Additions

For those looking to customize their soup or enhance its flavors further, consider the following optional ingredients:

  • Shallots: Add finely chopped shallots for a sweeter, more nuanced flavor.
  • Parmesan Cheese: Mix a little Parmesan with Gruyère for a nuttier topping.
  • Herbs de Provence: Sprinkle this classic French herb blend for added depth.
  • Truffle Oil: Drizzle a small amount for a luxurious touch.

Tips for Success

To ensure your Creamy French Onion and Mushroom Soup turns out perfectly, follow these tips:

  1. Take Your Time with Caramelization: The key to deep, rich flavor is slowly caramelizing the onions. Rushing this step will compromise the soup’s base.
  2. Choose Quality Wine: A dry white wine like Sauvignon Blanc or Pinot Grigio enhances the dish without overpowering it.
  3. Fresh Herbs Matter: Using fresh thyme and sage makes a significant difference in flavor. If unavailable, use high-quality dried herbs.
  4. Toast the Bread Properly: Ensure the bread is thoroughly toasted before broiling to prevent sogginess.
  5. Broil with Care: Watch the cheese topping closely to avoid burning. Aim for a bubbly, golden-brown finish.

Instructions

  1. Caramelize the Onions: Melt the butter in a large Dutch oven over medium-high heat. Add the onions and honey, stirring occasionally for 10 minutes. Gradually add 3/4 cup of wine, 1/4 cup at a time, letting it cook into the onions. Continue for another 10-15 minutes until deeply caramelized.
  2. Add Mushrooms and Herbs: Stir in garlic, mushrooms, thyme, and sage. Season with salt and pepper. Cook for 3-4 minutes.
  3. Build the Soup: Pour in the remaining 1/2 cup of wine, broth, Worcestershire sauce, and bay leaves. Bring to a simmer and cook for 10 minutes. Stir in the cream and simmer for another 5-10 minutes. Remove and discard bay leaves. Adjust seasoning as needed.
  4. Prepare the Bread: Preheat the oven to 400°F. Arrange bread slices on a baking sheet and toast for 10-15 minutes until dry. Switch to broil.
  5. Assemble and Broil: Ladle the soup into oven-safe bowls, add a slice of toasted bread, and top with Gruyère cheese. Place bowls on a baking sheet and broil for 3-5 minutes until the cheese is melted and golden.
  6. Serve: Garnish with fresh thyme and serve immediately.

Description

The final dish is a masterpiece of layered flavors and textures. The rich caramelized onions and earthy mushrooms are perfectly complemented by the creamy broth. The toasted bread adds a satisfying crunch, while the melted Gruyère provides a gooey, savory topping. It’s a dish that brings warmth and comfort to every bite.
